Abstract

Introduction: The prevalence of horizontal neck lines as a cosmetic concern is widely acknowledged, yet the available treatment options are limited, and no studies have investigated the use of polydioxanone-barbed threads. These threads, characterized by a finely braided structure, function as a scaffold to attract regenerative factors and facilitate the migration and proliferation of cells. This study aims to evaluate the outcomes of concurrent application of braided polydioxanone-barbed threads for addressing horizontal neck wrinkles.

Methodology: A retrospective case series involving four female participants (aged 41, 43, 45, and 46) treated with polydioxanone-barbed threads for horizontal neck wrinkles between January 2023 and July 2023 was conducted. Adult patients were assessed at an 8-week follow-up, revealing a significant reduction in wrinkle intensity based on the Horizontal Neck Wrinkle Severity Scale.

Results: The analysis of horizontal neck lines demonstrated a notable decrease in wrinkle intensity according to the Horizontal Neck Wrinkle Severity Scale at the 8-week mark, and this improvement maintained statistical significance. Both patient Global Aesthetic Improvement Scale (GAIS) scores (90%-100%) and physician GAIS scores (100%) were rated as excellent.

Conclusion: The subdermal application of polydioxanone-barbed threads for horizontal neck lines proves to be a secure and efficacious approach for treating horizontal neck wrinkles, with no observed Tyndall effect. This technique shows promise for rejuvenating the skin in the horizontal neckline region.

Keywords: horizontal neckline; neck wrinkle; polydioxanone; skin rejuvenation; thread lifting.

A 43‐year‐old woman received four braided polydioxanone‐barbed thread threads with a length of 60 mm (A, before treatment and B, 8 weeks after the treatment). After 8 weeks, the grading of the Horizontal Neck Wrinkles Severity Scale improved from a score of 3 to grades 1 and 2, as noted by both physicians.

A 46‐year‐old woman received four braided polydioxanone‐barbed thread threads with a length of 60 mm. Both physicians initially graded the Horizontal Neck Wrinkles Severity Scale with a score of 2, but after 8 weeks, patients with a score of 3 showed improvement, receiving a grade of 1 from both physicians.
